It ships without a motor and includes a durable bracket and sliding mechanism designed to lift and lower the glass reliably.

How durable and quiet is the FINDAUTO regulator compared with OE parts?

This regulator is built to OE-level specifications and has been cycled thousands of times in vehicle-door tests to check longevity and noise. The bracket and sliders use reinforced materials to minimize flex and vibration, resulting in smoother travel and reduced squeaks.

• Durable bracket and slide components for reduced shaking
• Tested through repeated cycles to confirm lifespan
• Engineered to slide smoothly and quickly without excess noise

Do I need the motor too, and how do I install the regulator?

This listing is for the regulator assembly only — it does not include the motor. If your existing motor is functional, you can reuse it; if not, purchase a compatible motor separately. Installation typically involves removing the door panel, disconnecting the motor, unbolting the old regulator, and bolting in the new unit before reattaching the glass and testing movement.

• Motor: not included — reuse existing or buy separately
• Basic steps: remove door panel → detach motor → swap regulator → test movement
• Professional installation recommended if unfamiliar with door mechanisms

What should I check before buying to avoid a return?

Double-check your vehicle year, the door side (rear left / driver side), and the part reference numbers to ensure compatibility. Inspect your existing motor and mounting points to confirm the regulator will mate correctly with the glass and fasteners in your door.

• Confirm year: 2016, 2017, 2018, 2019, or 2020
• Confirm location: rear left (driver side)
• Compare reference numbers: 83471C5000, 83471C6000
• Inspect motor and mounting hardware prior to installation

Who is this part for? This FINDAUTO rear left window regulator is intended for Kia Sorento owners, independent mechanics and DIY enthusiasts who need a reliable, OE-spec replacement without a motor. It’s a practical choice when the window glass moves unevenly, the regulator has broken gear teeth, or the existing track is worn; technicians will appreciate the tested durability and direct-fit design that speeds up the repair.
